The Saint Valentine's Day Massacre was the murder of seven members and associates of Chicago's North Side Gang on Saint Valentine's Day 1929. The men were gathered at a Lincoln Park, Chicago, garage when between four and six men entered, two of whom were disguised as police officers. The seven men were lined up facing a wall and shot with Thompson submachine guns and a sawed-off shotgun; seventy rounds were fired from the Thompsons, and one cartridge was discharged from the shotgun. Six of the victims died immediately; one lived for a short while but refused to identify the killers.
